I had a lovely cocktsil last night in a bar called El Duderino in Jönköping, Sweden. It was called La Verde and was comprised of mescal, lime, agave and chartreuse ( yellow VEP), chartreuse elixir and egg white with a line of Bunnahabhain Toiteach floated on top.
It didn't last long enough to take a picture. It was Incredibly herbal and smokey. I can't wait to try it at home.
